Title: Fluid distributor
IPC: G01N1/18
Filed: 1961-09-06
Abstract: 945,763. Bottling. UPJOHN CO. Sept. 6, 1961 [Oct. 14, 1960], No. 32028/61. Heading B8T. A collecting and distributing device for fluid material comprises a vertically reciprocable collecting chamber 48 having a discharge operable from when the chamber contains a first predetermined amount of fluid until the chamber contains a second predetermined amount of fluid, a support on which may be mounted receptacles 51, 52, 53 for receiving fluid material from a discharge pipe 54, means for biasing the chamber vertically upwards with a force which has a value of between the gravitational forms on the chamber before and after discharge and means for causing relative rotation between the chamber and the receptacles support upon downward movement of the chamber. The table 4 on which the chamber 48 is supported is in turn supported by an F- shaped member 10 which is connected to the frame 2 of the machine by parallel linkage 13, 14 and is thus vertically reciprocable. A crossmember 38 joins an extension of the link 13 to a similar extension on a corresponding link 34 on the other side and adjustably mounted on the cross-member 38 is a weight 18 which provides a counter balance for biasing the chamber 48 upwards. The supporting shaft 6 of the tubes 4 is rotatable in bearings in the limbs 9, 11 of the F-shaped member 10. A siphon 49 is arranged in known manner to predetermine the amount of fluid discharged, so that as fluid material enters the chamber 48 from a supply S and the level in the chamber rises, when the level reaches the height of the central portion of the U-shaped tube in the siphon, the contents are then siphoned through the discharge pipe S4. The weight 18 is adjusted so that the turntable 4 begins to move downwards at some point before the fluid level reaches the upper end of the automatic siphon 49. As the table 4 sinks a pawl 24, which is in engagement with one of a series of recesses 23 in the underside of the table, indexes the table through a predetermined arc of rotation, Fig. 5, and the discharge pipe 54 thus empties into the next receptacle 52, Fig. 4. As the chamber 48 empties and the weight 18 causes it to rise again the table 4 will not rotate and the discharge into the receptacle 52 will continue until the fluid level falls below the entrance of the siphon. Over running of the turntable is prevented by another pawl 44, adjustably mounted. A further pawl 31 acts to prevent reversal of the turntable due to the drag of the pawl 24 as it moves heat from one recess to another. Instead of using a counterweight, the table 4 may be biased upwards by a spring suitably disposed in relation to the linkage 13, 14. In another modification the table 4 is non-rotatable and its vertical reciprocation is arranged, through pawl mechanism similar to that already described, to index a rotary table which supports the receptacles into which the material is discharged.

Abstract: 935,046. Continuous-casting machines. E. A. OLSSON. Sept. 6, 1961 [Sept. 7, 1960], No. 32074/61. Class 83 (1). A method of continuous casting using a reciprocating mould comprises setting a free velocity of the mould in the casting direction substantially equal to a maximum casting velocity of the ingot and allowing movement of the mould in the casting direction at casting velocity below the maximum to be governed by the resistance, i.e. friction and adhesion resistance against relative movement between the mould and ingot. The mould frame 2 is supported on pistons in air or liquid cylinders 3. An electromagnetic valve 4 actuated through limit switches 7 connects the cylinders to atmosphere or a liquid reservoir via a relief valve 5, or to a source of pressure medium via a valve 6. The valve 5 is adjusted so that the free velocity of the frame in the downward direction, i.e. its velocity if there were no resistance due to the ingot does not substantially exceed the maximum casting velocity.
